the graph doesnt look too jagged to me by any means

Look at the air fuel thats what im refering to as jaged.. and yes my tune with 17 degrees is light years safer with its flat 11.8-1 - 12.0 air fuel then that tune is with its air fuel way lean across the whole thing and moving all over the place air fuel.

FUEL effects how much timing you can run .. the fater the air mixture the more timing you can safely run because the fater air fuel mixture makes the flame front burn slower.

anyone who knows anything about tuning will tell you 11.5-12.0 is proper air fuel for a supercharged or turbo charged vehicle.

13.5 is lean even for a naturaly aspirated car under load most will make best power around 12.9-13.2

and that supercharged car in the graph above is near 13.5 for most of the curve.


as for the owner of the car IM GLAD you retuned it because you would have hurt it with that first tune eventualy but for them to blame 02s as the reason they couldn't get the air fuel right is bogus.. the 02s are off during wide open throttle and do nothing to effect the fuel curve.

its under part throttle that the 02s are used.

your last tune is still boarder line as it wanders around between 12.5 and 12.0 air fuel.

again im not knocking your car or the kit just saying that tune was way off on the air fuel.

here is emilios actual graph.. the doted line on air fuel is the 11.8 reference notice the curve is between 11.8 and 12.0 for the ENTIRE run and no spikes dips Noticce the smoothing is set to ZERO .. so thats as jaged as it can get with smoothing set to 5 it would be perfect flat smoth lines the first graph i garentee would he prety rough looking with 0 smoothing instead of set to 5 setting smoothing to 5 is just a way of making rough curves look decent..



the lean climb at the end is due to the customers fuel pump being prety much maxed < sinlgle gt supercar pump with no booster > but he doesnt shift it past 6100 < 12.4 air fuel > so it will be ok unless he intends to add more power at wich point we will add a second pump or a boost a pump.

the lean you see at the start is part throttle and the dip in as it goes wide open throttle wich is perfectly normal we start our pulls then go wot so we can see to be sure the response time is acceptable instead of flooring it then starting the recording.
thats what a proper tune would look like.


Again im not bashing you I simply stated the tune < wich you did not do > was not safe
Why even post the graph your not even comparing cars with similar boost numbers with 12 psi the roush would easily eclipse 530-540 rwhp.

What are you using for a fuel pump on the car?

[psiperformance]

single ford gt super car pump its good to right at 475 rwhp with no preasure loss then it starts to peeter out. down the road we will most likley put a boost a pump into emilios car.

with a BAP the gt pump is good for 600 rwhp no problem

Dean, a friend of mine is selling me his Kenne bell boost a pump. I will be coming to you to install it. Did you here that Severo aka mrcouper, I'm coming for your pump. LOL

well i just got back from watching my car on the dyno, im ignorant so u can take what u want from this but his setup in the dyno software i belive calls for entering all the voltages of the mas air? The tuner him self goes only by the handheld wideband they put in the bungs, and goes by it alone. then when he prints the dyno sheets he puts no correction in it, usually not printing a/f's for that reason. But neways i watched them make a pull with the a/f meter in my hand and it never went over 12.2. Neways still loving that blue, but i had to go with black on mine, and a black whipple cause well i want to be blacked out, (and im to cheap for a polished kit so i can really look good lol). And if ya ever run across me on the freeway, watch out!

ill be using the KB BAP/60lb inj/ wiring upgrade/ gt super car pump should be good to 600

kwik46gt "Good numbers!!!!!!!! This is a Whipple install I did a couple weeks ago. The # were quite nice

Quartermile Solutions did the install and tuned by Fastlane in Houston"

@ psi--
DONT KNOW why, and cant see how you got bent outta shape and started with the dudes tune when it had nothing to do with Kwik..

Now on my other motor.. it was tuned by fastlane and the airfuel show 13.7 on the dyno graph but he said dont mind that its not correct .. I use a AEM UEGO wideband and it would read 11.8-12.2 under boost

A BAP would extend the single pump you have well into the high 500 low 600 rwhp range with ease far more power then your stock engine will take for long term so you will be fine with it.

so your saying he tunes your car with a wide band with a malfunctioning sensor ?
